DENNIS JIREAUME, OF DETROIT, MICHIGAN, ASSIGNOR OF ONE-HALF TO JOHNHOLTZ. OF DETROIT, MICHIGAN.

AGI'IATOR.

To all whom it may concern:

Be it known that I, DENNIS J. REAUME, a citizen of the United States ofAmerica, residing at Detroit, in the county of Vayne and State ofMichigan, have invented certain new and useful Improvements inAgitators, of which the following is a specification, reference beinghad therein to the accompanying drawings.

The invention relates generally to a mechanism for stirring or agitatingmaterials of various kinds, and particularly to a device of thischaracter especially designed for use in making butter, but it will beobvious from the following description that it may be put to otheranalogous uses, as may be desired.

The invention consists in the construction of the device, in thepeculiar arrangement and combination of parts, and in certain details ofconstruction, as will be more fully hereinafter described and pointedout in the claims.

In the drawings,Figure 1 is a vertical central section through anagitator embodying my invention; Fig. 2 is a sectional perspective viewof the top of the device, illustrating particularly the driving means;and Fig. 3 is a detail sectional perspective, showing the retainingmeans for the cover.

In the drawings thus briefly described, A represents a suitablereceptacle, in this particular instance a glass vessel, formed at itsupper end with a neck section B.

G are inclined ribs upon the neck portion that are adapted to form aretaining thread, and D .is the closure for the receptacle. The closureD, as shown, is made up of a plurality of sections. Thus, D is a ringmember," angle-shaped in cross section, adapted to be screwed upon theneck portion of the receptacle, the ring carrying depending lugs E thatengage the screw-threads C. Upon the inner edge of the ring described isformed an annular series of teeth F, which constitute an internal gearadapted to mesh with pinions hereinafter described carried by theheaters.

F is a disk or plate mounted upon the ring D for rotary movement.

G is an inner disk formed with an annular recess H extending about itsperiphery, and with complementary semi-circular recesses H in which thebeater pinions are adapted to be seated. This disk is rigidly attachedSpecification of Letters Patent.

to the disk F in any suitable manner, as by bolts I.

WVithin the receptacle described is a stirrer J, so fashioned as toextend from the top to near the bottom of the container and crosswisefrom side to side in proximity to the walls. In construction, thestirrer is preferably in the form of a frame made up of a centralspindle or shaft K, of polygonal cross section, rigidly attached to thedisk F of the closure, a cross bar L fixed upon the lower end of thecentral spindle, and side members M and N in the form of independentlyrotatable spindles uniting the cross bar with the closure. Thesecomplementary spindles are swiveled at their lower ends to the bar L,project upwardly through the disk G within the semi-circular recesses,and carry at their upper ends gear pinions Q, that mesh with theinternal gear F. P are smaller disks secured one upon each spindle tobear against the under face of the disk G. The lower cross bar Ldescribed terminates at its ends in blade members a, while the centralspindle K, and each of the side spindles is provided with a series ofbeater blades, as O, the several groups of blades being adapted tointerengage in the manner indicated in Fig. 1.

In the operation of the device, the stirrer proper is removed with theclosure from the receptacle, and the material that is to be agitatedplaced therein. The closure is then screwed upon the vessel, and throughthe agency of a handle, as R, the disk F rotates. This carries thestirrer frame in its entirety, causing the latter to rotate within thereceptacle, giving the entire mass of material therein a circularmovement, and at the same time, through the fixed internal gear, theside portions of the frame, constituting the heaters, independentlyrotate, and in directions opposite to one another. In this manner all ofthe material within the receptacle is intimately mixed or agitated in athorough and effective manner and within a minimum space of time.

What I claim as my invention is:

1. In an agitator, the combination with a receptacle, of a closurecomprising a stationary and a rotary member, a central spindle fixed toone of said members, spindles arranged upon opposite sides of saidcentral spindle and journaled in said last-mentioned member, beater armsupon said spindles and means carried by one of said closure members forcausing the simultaneous rotation of the side spindles.

2. In an agitator, the combination with a receptacle, of a closurecomprising a member having a fixed engagement with the receptacle and arotary disk, a stirrer secured to said disk, and a drive connectionbetween i rece tacle of a closure com risin a rin b t) "he receptacle,and means carried by and tachable with the closure for impartingcentrifugal movement to the vessel contents, and mechanism for stirringportions of the revolving mass in directions opposite to the centrifugalmovement.

In testimony whereof I afiix my signature in presence of two witnesses.
